Bus Hound: Cow poop-powered bus breaks speed record in the U.K

  

The UK’s poop-powered bus has set a speed record for a regular service bus with a top speed of 76.8 miles per hour (123.5kph). The bus’s engine is powered by cow poo or, more accurately, bovine manure-derived biomethane. In honor of its fecal fuel source, the bus is painted in black and white spots (like a cow).
